Soil Heavy Metal Accumulation and Ecological Risk in Mount Wuyi: Impacts of Vegetation Types and Pollution Sources

Land, Journal Year: 2025, Volume and Issue: 14(4), P. 712 - 712

Published: March 26, 2025

Soil heavy metal (HM) contamination has become a critical global environmental issue, predominantly caused by industrial and agricultural operations. This study focuses on Mount Wuyi, UNESCO biodiversity hotspot major tea production base, to examine vegetation-mediated soil HM accumulation under anthropogenic impacts. We analyzed nine HMs (Mn, Cu, Zn, Cd, Hg, As, Pb, Cr, Ni) across diverse vegetation types using geochemical indices Positive Matrix Factorization (PMF) modeling. The findings revealed Mn Zn were dominant elements, Cr Pb concentrations exceeded regional background values 3.47 1.26 times, respectively. demonstrated significant pollution levels, while Cd Hg posed the highest ecological risks. Vegetation type significantly influenced distribution patterns, with cultivated areas shrublands (including gardens) accumulating higher of from transportation sources. Notably, bamboo forests exhibited natural resistance contamination. PMF analysis identified four primary sources: urbanization (27.94%), transport–agriculture activities (21.40%), practices (12.98%), atmospheric deposition (12.96%). These results underscore need for implementing clean energy solutions, phytoremediation strategies, tea-specific detoxification measures maintain security sustainability in this ecologically region.

Accumulation Pattern and Potential Ecological Risk of Heavy Metals in Topsoil as Affected by Diverse Sources in Different Ecosystems in Western Dabie Mountain

Forests, Journal Year: 2024, Volume and Issue: 15(7), P. 1116 - 1116

Published: June 27, 2024

Soil heavy metal (HM) control has become a pressing global ecological and environmental issue, with significant focus on the western Dabie Mountain in China, region that is recognized for its barriers water sources. We analyzed concentrations, pollution status, potential risks of 10 HMs (i.e., Cu, +Pb, Zn, Cr, Ni, Co, Cd, As, Hg, Mn) topsoil different ecosystems this region. The effects four soil groups (Anthrosol, Fluvisols, Gleysol, Alisols) three texture types (sandy, clayey, loamy soils) above aspects were also analyzed. Positive Matrix Factorization (PMF) models performed to identify quantify sources contribution rates these HMs. Results showed level HM may be negligible, there was no risk. Of all metals, Pb Cd exhibited highest levels pollution. risk associated decreased from croplands urban further forests. Cu Co more likely accumulate Anthrosols, while Alisols Pb, Hg had higher overall clayey soils both than sandy soils. accumulation closely related organic matter clay contents. main can agricultural activities, parent material, mining, industrial vehicle emissions. These findings suggest special attention should paid Mountain. Future efforts reducing smelting, emissions, as well strengthening research migration patterns mechanisms

Distribution and risk assessment of heavy metals in soil in the Yellow River Basin (Heze - Tai 'an section)

E3S Web of Conferences, Journal Year: 2024, Volume and Issue: 573, P. 01014 - 01014

Published: Jan. 1, 2024

The presence of heavy metals in soil significantly impacts human agriculture and livelihood. Yellow Rive plays a crucial role the country's economic social development as well ecological security within its basin. After conducting measurements on distribution As, Hg, Cu, Pb, Cd Cr Heze - Tai 'an section River Basin, degree metal pollution investigation area was analyzed evaluated using potential risk index. anal- ysis revealed that concentration ranges Cd, Cr, As Hg were 0.054-1.109, 22.40-427.28, 6.00-108.40, 9-58.1, 1.5-46.8 0.002-0.706 mg/kg, respectively. average value individual eco- logical index is following order: > Cu Pb Cr. low, while moderate, which mainly caused by coal mining chemical enterprises.
